CD PLAYER: CD read by laser converted to PCM (a Data set pulses) and sent to a DAC which converts it to analog.
Several things affect the sound; the accuracy of the laser and error correction circuitry convert the CD on the fly to PCM and the DAC output stage used. All this is done in real time and the music output changes slightly each time you play the CD. Computer: CD read and error corrected accuratly because time not important, can be BIT perfect if using the EAC program. It can now be converted to a format like FLAC. FLAC takes up less space than PCM, so you can store more music and transmit it quicker. The FLAC can be sent to a Squeezebox by WIFI or ethernet. The electronic circuitry in the Squeezebox reconverts the FLAC to the PCM file (exact conversion: hence Lossless). The PCM is then sent to a DAC (built into the Squeezebox or external) which converts it to analog.The music output is always the same for the same music file. CD player and Squeezebox sound different for the same Music because the DAC output stage is different and the PCM input is variable on the CD player. With the Touch; it acts like a mini PC for handling music files and can handle up to 24/96 format, a cd is limited to 16/48. if you attach a Hard disc to the Touch, it can access the music files on that disc directly. if you connect the Touch to a network, the hard disc becomes a network disc and music files can be sent to it by other network users and even received from it. you can simulate the Squeezebox even Touch by using the free software in the download section. This will allow you to see how it handles music files and compare it to Itunes, you can even use Itunes to feed the Squeezebox (except for FLAC files). The only thing you need for the TOUCH is some way of getting music files too it and amplyfiying the Sound out of it. -- c3p0 ------------------------------------------------------------------------ c3p0's Profile: http://forums.slimdevices.com/member.php?userid=20721 View this thread: http://forums.slimdevices.com/showthread.php?t=72246 _______________________________________________ Touch mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/touch
